Which is better OPC 43 or PPC?

PPC produces highly durable concrete as it has low water permeability compared to OPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing. And PPC is cheaper also compared to OPC. OPC is highly applicable where fast pace of construction is required.

What is meant by 43 Grade OPC?

OPC 43 means that the cement is expected to reach a compressive strength of 43 MPa in a cube cast by 28 days.

Can we use OPC and PPC cement together?

Hence, both OPC & PPC can be a substitute to each other but only with a better quality control & by adopting best construction practices. So, for the construction of concrete slab both the OPC & PPC cement can be used.

What is the specific gravity of OPC 43 grade cement?

3.15
Cement In this experiment 43 grade ordinary Portland cement (OPC) with brand name ultra tech was used for all concrete mixes. The cement used was fresh and without any lumps IS 8112 The specific gravity of cement was found to be 3.15.

Is UltraTech Super OPC or PPC?

UltraTech Super is a PPC grade cement. Ultratech Super cement has high degree of cohesion and workability in concrete and mortar.

Is PPC better or OPC?

PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks & reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).

Is PPC cheaper than OPC?

PPC has low initial setting strength than OPC but it hardens over time with proper curing. PPC is cheaper than OPC.

What is the difference between OPC and SRC cement?

SRC (Sulphate Resisting Cement) SRC can be used for structural concrete wherever OPC or PPC or Slag Cement is usable under normal conditions. The use of SRC is particularly beneficial in such exposure/service conditions, where the concrete is exposed to the risk of deterioration due to sulphate attack.
